Problems solved by technology

[0003] At present, the organic fertilizer in the co-cultivation mode of shrimp and rice is a traditional fertilizer, which has the advantages of comprehensive nutrition, but the fertilizer effect is slow, the process of being used by plankton is long, and a large amount of oxygen in the water body is consumed in the process of decomposition and mineralization , it is easy to cause water pollution, which is unfavorable to the growth of crayfish, and the use of organic fertilizers is also limited by seasons, mainly used as base fertilizers in win

Abstract

The invention discloses a special bio-organic-inorganic compound fertilizer for shrimp rice fields and a preparation method thereof. The special bio-organic-inorganic compound fertilizer for the shrimp rice fields comprises 3 to 10 percent of amino acids, 10 to 15 percent of activated humic acid, 35 to 45 percent of an inorganic nitrogen fertilizer, 15 to 25 percent of an inorganic phosphate fertilizer, 15 to 25 percent of an inorganic potassium fertilizer, 0.2 to 1 percent of a composite microbial agent, 1 to 3.5 percent of kaolin and 0.1 to 0.5 percent of a coating agent, wherein the composite microbial agent comprises bacillus subtilis, bacillus laterosporus and bacillus mucilaginosus in a weight ratio of 1-2:1:1-3. The special bio-organic-inorganic compound fertilizer for the shrimp rice fields has exquisite formula, makes up for various deficiencies of organic fertilizers and inorganic fertilizers, realizes rapid fertilizer and water application in low temperature seasons, provides appetizing materials for young shrimps, prevents moss in advance, can also promote the development of roots of rice and aquatic plants, realizes rapid survival, and is beneficial to maintaining therelatively stable effect of a water-soil-animal-plant system.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special biological organic-inorganic compound fertilizer for shrimp and rice fields and a preparation method thereof. Background technique [0002] "Shrimp and rice co-cropping" is a farming model that combines planting and breeding, that is, crayfish are cultivated in paddy fields and rice is grown for one season. During rice cultivation, crayfish and rice grow together in the paddy fields. This model can not only improve the benefits of planting (raising), but also reduce the use of pesticides and chemical fertilizers, and improve the organic matter content of paddy fields, which has high economic and ecological value. Shrimp rice cultivation is different from conventional rice cultivation or aquaculture, focusing on the comprehensive benefits of rice and shrimp. In addition, due to the combination of planting and breeding, shrimp and rice co-culture has changed...
